I agree. I have logged timing in the past and it was below -5.



Could be. I will put a new tank of Sunoco 93 in tonight. Last tank was Marathon 93, which is what I usually run.

Changes in the last 6 months include new plugs and R8 coil packs, purely from a preventative maintenance stand point. I will check the plug gap this week.

Are you having any misfires?

Add the Sunoco and Lower the gap to 0.025 and try some new logs.

Very very rarely. I logged last week and under normal driving and full throttle my miss fire counter captured 1 miss fire. I will try your recommendations.

APR v2.0 K04 93 octane
APR Intercooler
APR Stage 1 Carbonio
AWE Turbo back exhaust

Temp: 45 degrees
Rel. Humidity: 38%

All logs were done in 3rd gear.






That's the most timing pull I've seen from any APR 93oct file. Still not way out of line, but maybe Arin or Bronson can comment further.

What jumped out at me was your MAF readings. Among the lowest I've seen actually.

You guys should graph ignition angle as well so we can see how much timing advance you are running after the pull

I can't comment on the timing pull, but the reason the maf numbers are low is because the logs weren't done to/near redline. He has another 1k RPMs in his powerband.

^Dude I have been trying for the past couple of days to graph my logs lol. I'm getting there but I'm not there yet. Email John@UNI, or Grambles. They can do it for you

Thanks to John@Unitronic for graphing these for me. Mods are in sig. I am DSG and this was a 4th gear pull done in 60 degree weather.

BIG Thanks to John@UNI for graphing these logs for me.

12' GLI / APR v2 K04 93oct with stock exhaust..









They seem to follow the typical APR pattern. I have a feeling the UNI 2+ tune with higher timing would help with the lack of responsiveness I am yearning for!

Why is it some logs show actual to be more than requested while others meet requested?

I need to stop being lazy and log my car.
There's a serious lack of GIAC k04 logs on this forum...
